How to install, build and use XDP related packages

PAGE UNDER CONSTRUCTION

There are multiple software packages that need to be downloaded, compiled, and installed for XPD-related code to run

Installing libbpf

1st: install the libelf library

sudo apt-get install -y libelf-dev

2nd: get and install the libbpf related files

export DESTDIR=<installation dir>
export PREFIX=""
git clone https://github.com/libbpf/libbpf.git
cd libbpf
cd src
make install

3rd: get and install the libxpd related files

export DESTDIR=<installation dir>
export PREFIX=""
git clone https://github.com/xdp-project/xdp-tools.git
cd xdp-tools

Follow the instructions in xdp-tools/README.md file for compilation. Note: there is no need to do a git submodule on libbpf.

Instructions are at https://github.com/xdp-project/xdp-tutorial , go to the setup_dependencies.org link at https://github.com/xdp-project/xdp-tutorial/blob/master/setup_dependencies.org

This tells us to

sudo apt install clang llvm libelf-dev libpcap-dev build-essential (but since we already loaded libels-dev)
sudo apt install clang llvm libpcap-dev build-essential
sudo apt install linux-headers-$(uname -r)
(how does xdl-tools find bpftool, we may have to use xdl-tutorial, but we'll see)
./configure

Clone the repository

git clone --recurse-submodules -b v1.50 --depth 1 --shallow-submodules https://github.com/grpc/grpc

Build the package
